Parameter Description Value for This

Example

all.data_buffering A non zero value activates data buffering (local or remote, according

to what was configured in the parameter conf.nfs_data_buffering seen

before). If local data buffering, a file is created on the Cyclades-TS; if

remote, a file is created through NFS in a remote server. All data

received from the port is captured in this file. If local data buffering, this

parameter means the maximum file size (in bytes). If remote, this

parameter is just a flag to activate (greater than zero) or deactivate

data buffering. When local data buffering is used, each time the

maximum is reached the oldest 10% of stored data is discarded,

releasing space for new data (FIFO system) - circular file. When

remote data buffering is used, there's no maximum file size other than

the one imposed by the remote server - linear file. This file can be

viewed using the normal Unix tools (cat, vi, more, etc.). See the

section on data buffering for details.

all.DB_timestamp A non zero value activates time stamp recording in the data buffering

file. This parameter is meaningful only if data buffering option is active.

In case time stamp recording is on, input characters will be

accumulated until either a CR or LF character is received from the

serial port or the size of the accumulated data reaches 256 characters.

Then, the accumulated data will be recorded in the data buffering file

along with the current time.

all.syslog_buffering When non zero, the contents of the data buffer are sent to the syslog-

ng every time a quantity of data equal to this parameter is collected.

The syslog level for data buffering is hard coded to level 5 (notice) and

facility conf.DB_facility. The file /etc/syslog-ng/syslog-ng.conf should

be set accordingly for the syslog-ng to take some action (please see

Appendix G for syslog-ng configuration file).
